Abstract (en)

[origin: WO9944832A2] A direct electrostatic printing device and method for printing an image to an information carrier with increased edge smoothness. By controlling the transport of toner particles, dots can, if needed, be adjusted from the exact alignment of a dot matrix to thereby enable formation of smoother edges that are not aligned with the dot matrix. The control of toner particle transport can be effectuated by time displacement of the opening and closing of the apertures, and/or modification of the deflection voltages. A further improvement is the control of the deflection voltages for controlling the size of the dots, alone or in combination with the position modification of the dots.
